Figure 1. Event Study Estimates of the Association of COVID-19 Vaccine Mandates With Nursing Home Staff Vaccination Coverage and Reported Staff Shortages.

Estimated weekly differences and 95% CIs in staff vaccination coverage (A) and reported staff shortage rates (B) between mandate states (with and without a test-out option) and nonmandate states after a mandate announcement (denoted by the vertical dashed line). Estimates were obtained from an event study regression with facility and calendar week fixed effects. All estimates are relative to the week prior to mandate announcement (week = −1), denoted by an open circle in the figure. Full details are available in eAppendix 2 in the Supplement. Event week = −6 contains estimates for event weeks ≤ −6. Event week = 10 contains estimates for event weeks ≥ 10.
